Boston Gear D50B25 Roller Chain Sprocket

Boston Gear D50B25 is a double-strand roller chain sprocket engineered to drive ANSI No. 50 chain in compact power-transmission layouts, offering 25 teeth to balance speed and torque in demanding equipment. Made from steel, this sprocket is designed to mesh with two strands of No. 50 chain, which uses a 5/8 inch pitch, enabling load sharing across both chains and helping to extend component life in continuous-cycle operation. The tooth form and geometric accuracy are specified to maintain consistent engagement with roller links, promoting even wear and reliable performance under typical industrial duty cycles. Sprockets in this family are designed for straightforward integration with standard shafts and mating components, and they are commonly used in conveyors and other automated machinery where a robust, two-strand drive is advantageous and reliability is essential.
